In this study, it was aimed to determine the effects of organic and inorganic fertilizer applications at different rates on the yield and development of maize plant. The research was carried out in three replications in greenhouse conditions, according to the randomized plot design, in plastic pots with a capacity of three kg. Applications in research; control, conventional fertilization, gypsum (1% and 2% w/w), anhydrite (1% and 2% w/w), calcite (1% and 2% w/w), perlite (1% and 2% w/w), vermicompost (5% and 10% w/w) and animal manure (5% and 10% w/w). Maize was used as the test plant. Maize plant was harvested approximately 60 days after planting and analysis of dry matter production and nitrogen, phosphorus, potassium, calcium, magnesium, iron, zinc, manganese and copper were made. According to the results of the research, the highest dry matter production was determined at 15.4 g pot-1 and 10% of the vermicompost application. This application was followed by conventional fertilizer application (13.64 g pot-1). In addition, vermicompost application in general had higher values in macro and micro element concentrations of maize plant.

Macrofungi have long been used as food and medicinal purposes by humankind. This study aimed to identify a macrofungus sample collected from Niğde, Türkiye in 2019 via molecular techniques and determine the content of total phenolic compounds, antioxidant and antimicrobial activities. According to data obtained from the sequence analysis of ITS fragment of rDNA the macrofungus sample was identified as Bjerkandera adusta (Willd.) P. Karst (1880). The sample was extracted with ethanol and methanol. Total phenolic compound content, antioxidant activity via DPPH scavenging method and antimicrobial activity via disc diffusion method of B. adusta was determined by using these extracts. The amount of total phenolic compounds was found as 772.28 µg GAE/mL for a methanolic extract of B. adusta. The ethanol extract of B. adusta showed 79.66% scavenging activity of 0.1 mM DPPH solution. The highest inhibition zone diameter was measured as 28±1 mm against P. aeruginosa by ethanolic extract, while the lowest antimicrobial activity was found in 15 µL methanol extract against S. typhimurium with an inhibition zone diameter of 8.7±1.2 mm.

Abdulrezzak Memon | Nuriye Meraklı
Arabidopsis thaliana has eight genes encoding members of the type P1B heavy metal–transporting ATPase, subfamily of the P-type ATPases. We focused our study on four ATPases, mainly HMA1, HMA2, HMA3, and HMA4, which are closely related and most similar in their sequences. We carried out the bioinformatics analysis of these metal ATPases and obtained their structure in A. thaliana, A. halleri, and the other heavy metal accumulators in Brassica spp. A. thaliana is a model plant for research because of the duplications and other evolutionary events. These evolutionary events provided a chance to elucidate their regulation and function in the cell. All previous bioinformatics analyses have given some information about their structure, but not much work has been done on their structural components and interactome analysis. Experimental determination of 3D structures is essential to understand better these proteins’ function, which is crucial for the proper functioning of all plant cellular processes. Especially, docking sites and domains need to be worked out to understand the role of these transporter proteins and their interaction in plant cells. These bioinformatic analyses will help the researcher understand these ATPases’ role in detoxifying the toxic metals from the cells of accumulator plants. Further research on gene cloning, gene expression, and generating new accumulator plants for phytoremediation is needed to reclamation polluted soils from toxic heavy metals.

In Turkey, three species of mulberries, white (M. Alba), black (M. Nigra), and red-purple (M. Rubra) are grown commonly. These widely can be consumed fresh as well as dry. However, its rapid post-harvest decay raises major concerns about the sustainability of the fruit for both food and economic purposes. In this regard, besides the fresh consumption of black mulberry fruit, it can consume as dried it also offers an alternative way. In this study, it was aimed to compare some quality parameters in fresh and dry samples of Morus rubra fruits grown in Tokat. It was applied different temperatures to Morus rubra fruits that at collected in two different maturity levels (semi-ripe and full-ripe). In the drying process, mulberry fruits were dried in a hot air dryer at 40, 50, 60, and 70°C. Total phenol, Total phenol, total monomeric anthocyanin, total antioxidant capacity, colour values (L, a, b) chroma, hue (ho), and browning indices values will be measured in fresh and dried products. In addition, different mathematical models will be tried by constantly noting the weight drops of the products at certain time intervals and determining which mathematical model will best predict the drying kinetics

The present study was conducted to evaluate the water quality of the inlet, irrigation outlet, and edges linked to Nuwarawewa reservoir, Mahakanadarawa reservoir, Hurulu wewa reservoir, Sangilikandarawa reservoir, and Nachchaduwa perennial reservoir in Anuradhapura, Sri Lanka. Water samples were taken from a designated position of each inlet, irrigation output, and edges in the second inter-monsoon, northeast monsoon, and first inter-monsoon seasons. Water quality indicators such as pH, electrical conductivity (EC), total dissolved solids (TDS), Na, K, Ca, Mg, Sodium Adsorption Ratio (SAR), NO3- -N, NH4+-N, dissolved reactive phosphorus (DRP), and heavy metals (Cd, As, Pb, and Hg) concentrations were measured in each water sample. Data was analyzed using SPSS statistica software. Considerable temporal fluctuations in water quality indicators were detected in inlets, irrigation outflows, and edges over the research period. The findings revealed that NO3- -N, NH4+-N, and DRP in Sangilikandarawa reservoir during the northeast monsoon were close but not above the FAO (1985) maximum levels guidelines for irrigation water. pH, EC, TDS, and heavy metals (Cd, As, Pb, and Hg) in all the other tanks were within permitted values according to WHO drinking water quality standards and FAO (1985) guidelines for irrigation water. This finding further demonstrated that the consequences of surrounding land use on water pollution in inlet water canals linked to Sangilikandarawa and Nuwarawewa are greater. It could be concluded that a pollution management plan needs to be implemented in order to stop further pollution.

Alper Zöngür | Naci Değerli
Six different temperate zone species of Cyprinidae family members, which are adapted to different harsh environmental conditions, were analyzed versus cold-acclimated Salmonid. Hemoglobin diversity in the studied species was investigated with a modified form of isoelectric pH: 3.5-10 ampholite system. 6 isohemoglobin bands were observed for cold-acclimated Oncorhynchus mykiss 8 isohemoglobin were observed for Chalcalburnus tarichi 9 for Cyprinion macrostomus and Sarkisla (Sivas) Cyprinus carpio, 11 Garra rufa and finally 12 for Todurge (Sivas) Cyprinus carpio. Cathodic/anodic ratios were found equal to 1for control and the fish adapted to available conditions. However, these ratios were found below 1 when environmental conditions were changed for fish, which are adapted to these poorly oxygenated conditions. Different environmentally adapted fish species are representing various isohemoglobins bands pattern. The species used as a control group in this study shown the lower isohemoglobin bands form. On the other hand, different forms of temperate climate Cyprinidae family member are produced isohemoglobins bands pattern, and the number of these band were higher than control group, depending on different adaptation conditions. The majority of these protein bands were anadic and it can be said that fish are producing anodic hemoglobin protein, when environmental conditions was changed to poorly oxygenated milieu.

Colostrum quality produced by dairy cows varies considerably. The amount of immune protein content in colostrum has also high specific gravity. In this study, the specific gravity of colostrum (SGC) produced by 32 Holstein-Friesian cows with different parities in the first five milking after calving, and additionally, the fat content (FC), non-fat dry matter content (NFDMC) and somatic cell count (SCC) in the milk samples taken in the first five milking and on the fifth and 10th day milking of lactation were determined. The effects of parity and milking order on SGC, FC, NFDMC and Log10SCC were detected to be statistically significant. Parity x milking order interaction effect was found to be significant for SGC, FC and NFDMC, but its effect on Log10SCC was insignificant. Cows with three and upper parities had higher SGC, FC, NFDMC, and Log10SCC than cows in the first and second parities. While SGC (1055.09±1.20 mg/mL), FC (6.36±0.12%) and NFDMC (18.17±0.37%) obtained at the first milking decreased gradually in advancing milking, Log10SCC (5.90±0.028) level increased. The correlation coefficients of SGC with FC, NFDMC, and Log10SCC were low-medium, the coefficients between FC and NFDMC were moderately too high in the first three milking, and decreased and approached zero in advancing milking. It was observed that SGC remained high even in the fourth milking in some cows, especially in the third and higher parities. In conclusion, it has been revealed that not only colostrum obtained from the first milking, but also quality colostrum produced in subsequent milking can be used in calf feeding in dairy cattle farms. However, all this depends on the adoption of the strategy of determining the quality of colostrum with the help of a colostrometer in dairy cattle farms.
